Are you sure you want to delete this answer? Yes Sorry, something has gone wrong. How does Shakespeare differentiate between "good" and "bad" love in 'Twelfth Night'?
Wallace Sabine showed that the decay is approximately exponential and calculed the RT60 using what we know as the Sabine equation: See Why is sound absorption in water less than in air?
Acoustic impedance Z is the ratio of the acoustic pressure p, measured in Pascals, to the acoustic volume flow, measured in cubic metres per second.
Specific acoustic impedance z is the ratio of the acoustic pressure p, measured in Pascals, to the acoustic velocity, measured in metres per second.
We introduce and explain these in two separate pages. Acoustic impedance, intensity and power is an introduction in terms of physics and the wave equation.
What is acoustic impedance? Why is sound absorption in water less than in air? According to my text, for a 1 kHz signal in water the loss by medium absorption is about 0. In air, the loss is much greater: Imagine that we could take a very fast picture of certain properties of a sound wave during transmission.
The pressure varies from a little above atmospheric, to a little below and back again as we progress along the wave. Now the high pressure regions will be a little hotter than the low pressure regions.
The distance between two such regions is half a wavelength: A small amount of heat will pass from hot to cold by conduction. Only a very small amount, because, after half a cycle 0.
Although it is small, this non-adiabatic non-heat conserving process is responsible for the loss of energy of sound in a gas. What happens when we change the frequency? The heat has less distance to travel shorter half wavelengthbut less time to do so shorter half period.
These two effects do not cancel out because the time taken for diffusion of heat or chemical components is proportional to the square of the distance.
So high frequency sounds lose more energy due to this mechanism than do low. This, incidentally, is one of the reasons why we can tell if a known sound is distant: Another contributing effect is that the relative phase of different components is changed.
Three different parameters make the loss less in water.
First, sounds travels several times faster in water than in air. Although the density of water is higher by a factor of aboutthe elastic modulus is higher by a factor of about 14, So, for a given frequency, the wavelength is longer and the heat has further to travel.
Second, the water does not conduct heat so rapidly as does air. Not counting the fact that you probably wear more clothes when out of the water. Third, the temperature of water rises less under a given imposed pressure than does that of air.
Why do the sounds of two musical instruments always reinforce, and never cancel out? However, when two instruments play the same note, it is always louder, and never softer.
The answer to this involves several different effects that complicate the sound of musical instruments. Nevertheless, when two instruments are nearly but not exactly in tune, you do hear the phenomenon of beats listen to the sound files of beats. This is an example of constructive and destructive interference: When the two waves are in phase it sounds loud but, when they are out of phase it is soft.
There are several reasons for this: And they often have vibrato. Even if they were of equal amplitude, it is unlikely that you would be equally distant from both. Further, this effect is enhanced by the logarithmic response of your ears see what is a decibel?
So even if you achieve cancellation with this precision hard to dothe effect is not as spectacular as you might expect.
Even when the conditions are such that two harmonics cancel, other harmonics may not.In Twelfth Night, love is seen as similar to death, because both prose a threat, or at the very least, a challenge to the singular self that is afraid of change.
To be able to love another requires that one must accept change, to accept that one cannot entirely control one's fate, or even one's will. Write an essay that explores Shakespeare’s treatment of the theme of love in Twelfth Night.

Twelver theology, which mainly consists of five principles, has formed over the course of history on the basis of the teachings of Quran, and hadiths from Muhammad and the Twelve Imams (especially Jafar al-Sadiq), and in response to the intellectual movements in the Muslim world and major events of the Twelver history, such as the Battle of Karbala and the occultation of the twelfth .

William Shakespeare's Twelfth Night - William Shakespeare's Twelfth Night Twelfth night is a play written by Shakespeare. It is a comedy about messed up love lives (Orsino, Olivia and Viola’s love triangle), hidden identity, revenge and being selfish.
